Need for interrupts

Interrupts are essential in computer systems as they enable the CPU to respond to asynchronous events, allowing it to prioritize critical tasks and manage multiple processes efficiently. They facilitate real-time processing by interrupting the current execution flow to handle time-sensitive operations, such as input from peripherals or system errors. This mechanism improves overall system responsiveness and resource utilization, as the CPU can perform other tasks instead of waiting for events to occur. Additionally, interrupts help maintain system stability and performance by allowing the operating system to manage resources dynamically.
